Changsha DLADTO Rebar Splice Co., Ltd

Rebar Coupler is designed to produce a full-strength mechanical joint between reinforcing bars. Today, I will share with you how to detect the tensile strength of the  rebar coupler . Let's get a close look. 1. Process Inspection Before and during the construction of the steel bar connection project, conduct a process inspection for each batch of incoming splices. There shall be no less than 3 splices of each type of steel bar during process inspection. The base material of the splice specimen shall be taken tensile strength test. 2. On-site Inspection The on-site inspection of splices shall be carried out according to the acceptance batch, and the joints of the same grade, type, and specification of the same batch of materials shall be adopted under the same construction conditions. An acceptance batch of 500 will be conducted for inspection. For each acceptance batch of splice, three specimens must be randomly selected from the engineering structure for unidirectional tensile tes...

Cold extrusion rebar coupler   connection is a new technology for steel bar connection in the construction of reinforced concrete structures. At present, it is used in some large hydropower projects in our country, such as the Three Gorges Hydropower Station, the Xiaolangdi Project, the Gongboxia Hydropower Station, and the Laxiwa Hydropower Station.  Features of steel sleeve cold extrusion technology: (1) The cold extrusion rebar coupler connection technology is simple and easy to master. (2) The cold extrusion rebar coupler is fast in construction, which can save a lot of time in construction. (3) The cold extrusion rebar coupler can reduce the engineering cost. (4) The cold extrusion rebar coupler is suitable for the radial extrusion connection of ribbed steel bars with steel bar diameters of φ16-φ40 in reinforced concrete structures. Changsha DLADTO Rebar Splice Co., Ltd  is a professional rebar coupler producer, we have been in this field for a long time with custome...

Upsetting Forged Rebar Couplers offer a full strength connection together with enhanced fatigue resistance. Followings are the main features of  Upsetting Forged Rebar Coupler . 1. The splice is as strong as steel bars. The performance meets the requirements of the highest grade (Grade I) in the current industry standard "Technical Regulations for Mechanical Connection of Steel Bars" (JGJ 107-2016). 2. Faster construction, convenient inspection, reliable quality, and no project quality risks. 3. The connection does not require power or other energy equipment, and the operation is not affected by the climate and environment. It can be operated in the wind, snow, rain, underwater, and flammable gas environment. 4. On-site operation is simple,  and only simple training is required. The operation of Upsetting Forged Rebar Coupler is very simple and convenient. Generally, after a short time of training, workers can grasp and make qualified splices. 5. Rebar thread processing can b...

Threaded rebar coupler   also called straight threaded rebar coupler and rebar connectors, its specifications are: M12, M14, M16, M18, M20, M22, M25, M28, M32, M36, M40. Here we will introduce you the difference between national standard threaded rebar coupler and non-standard threaded rebar coupler. The national standard threaded rebar coupler has a clear stencil, while the non-standard coupler does not have the stencil, and the price is lower.Also the non-standard coupler has thinner outer diameter and short length compare to national standard coupler. The most commonly used straight threaded rebar coupler is HRB400, and there are also HRB500 for engineering. Changsha DLADTO Rebar Splice Co., Ltd  is a professional rebar coupler producer, we have been in this field for a long time with customers for all over the world. If you have any inquiry, welcome to contact us.

  Rebar couplers  are components which connect two reinforcing bars in longitudinal direction, forming a  mechanical splice .  According to the requirements, the diameter of 10~50mm steel bar straight thread rebar coupler can be made. So, what are the advantages of rebar coupler?  1. Convenient connection: even in a narrow place where the rebar is dense it can also operate flexibly. Convenient construction and high efficiency: the steel bar connecting sleeve is prefabricated by the factory, and the quality is guaranteed. Each group of wire rolling machine equipment has nearly 400 machinable joints, with incomparable advantages, no pollution during construction, and no open fire.  2. Easy to inspect: Do not need to use specific inspection equipment, and you can measure the quality of the splice by checking the thread of the steel bar. Strong applicability: applicable to the reinforcement connection of all seismic and non-seismic reinforced concrete structure...

Half grouting rebar coupler   is a important type of grouting connection, which is used to connect vertical steel bars of prefabricated concrete components, such as the connection of main bars of prefabricated shear walls, prefabricated frame columns, and prefabricated decorative panels. One end of the half grouting rebar coupler is mechanically connected to the steel bar and the other end is a grouting cavity, which is anchored with the steel bar through the grouting material. JM-GT series half grouting rebar coupler are grouting connection sleeves with straight threads, it including GT4 (connecting with HRB400 steel bars), GT5 (connecting with HRB500 steel bars) grouting rebar coupler. In addition, there are HG-type half grouting rebar coupler specially used for export, and the diameter of connecting steel bars ranges from 12mm to 40mm.
